I’m building a system with some remote desktop capabilities. The client is considered every computer which is sharing its desktop, the server is considered a central server with a database which receives the images of all the multiple desktops. On the client side, I would like to build two projects: A windows service application and a VCL forms application. Each client app would presumably be running under a different user account on the computer, so there might be multiple client apps running at once, and they all send their image into this client service, which relays them to the central server.
The service will be responsible for connecting to the server, sending the image, and receiving mouse/keyboard events. The application, which is running in the background, will connect to this service some how and transmit the screenshots into the service. The goal is that one service is running while multiple “clients” are able to connect to it and send their desktop image. This service will be connected to the “central server” which receives all these different screenshots from different “clients”. The images will then be either saved and logged or re-directed to any “dashboard” which might be viewing that “client”.
The question is through what method should I use to connect the client applications to the client service to send images? They will be running on the same computer. I will need both the abilities to send simple command packets as well as stream a chunk of an image. I was about to use the Indy components (TIdTCPServer etc.) but I’m sure there must be an easier and cleaner way to do it. I’m using the Indy components elsewhere in the projects too.
Here’s a diagram of the overall system I’m aiming for – I’m just worried about the parts on the far right and far left – where the apps connect to the service within the same computer. As you can see, since there are many layers, I need to make sure whatever method(s) I use are powerful enough to accommodate for streaming massive amounts of image data.
Communicates among processes, you can use Pipe/Mailslots/Socket, I also think while sending a stream file Shared Memory maybe the most efficient way
